tests: Fix mountpoint test failure in build chroots.

The test assumed that / was a mountpoint. This is not always the case, for
example in pbuilder/cowbuilder chroots. So use / if findmnt verifies it is a
mountpoint, otherwise use the first mountpoint found. Skip the test if no
mountpoints are found.
